#18. In longitudinal waves are the vibrations parallel or at right angles to the direction of wave travel?
#19. Which of the following is an advantage of crude oil?
#20. What is the equation relating wave speed (v) distance (x) and time (t)?
1
#21. What is the name of the phase change from gas to solid?
#22. What is the approximate radius of an atom?
#23. Is oil renewable?
#24. How is fossil fuel usage changing as a percentage of total energy production worldwide?
#25. Calculate the distance travelled by the runner in the velocity/time graph.
The area under the graph = distance travelled
Split the graph into triangles and rectangles and calculate the areas. Then add together the areas.
Area of a rectangle = Length x Height
Area of a triangle = 1/2 x Length x Height
90m 120m 180m = 390m
NOTE: the graph starts at one second and not 0. Don’t be fooled, look at the axes carefully before attempting a question.
